Abstract

The invention relates to an electric energy quality on-line monitoring system, relates to the technical field of power supply and is used for solving a problem that the electric energy quality is inconvenient, timely, accurate and visual to understand in the prior art. The electric energy quality online monitoring system is characterized by comprising a monitoring device, a communication module and a remote control center, wherein the monitoring device comprises an analog quantity acquisition module and a processor module, the analog quantity acquisition module is connected with a detected three-phase circuit and is used for acquiring a sequence current signal of the three-phase circuit, a voltage signal of each phase of the three-phase circuit and a current signal of each phase of the three-phase circuit. The system is advantaged in that electric energy quality data can be obtained timely, accurately and visually.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to an online power quality monitoring system. Background technique [0002] In modern society, electric energy is one of the most widely used energy sources, and its application degree is one of the main symbols of a country's development level. With the development of science and technology and social economy, the demand for electric energy is increasing day by day, and the requirements for electric energy quality are also getting higher and higher. Power quality is of great significance to the safety of the power grid and electrical equipment, economical and efficient operation, product quality assurance, and maintenance of the normal order of people's daily production and life. With the increase of non-linear loads and time-varying loads in the electrical reference network, it brings problems such as harmonics, short-term voltage fluctuations (sags, swells and interruptions...
